READING DESK.

Application filed .Tune 12, 1922. Serial No. 567,615.

My invention relates todesks, particularly to `portable reading desks, andzthe objects of my invention are: first, to provide a desk ofl this class in which the deskportion may be variously shifted and positioned outwardly and' laterally with relation to its support; second, to `provide a desk ofl this class in which the desk* may be adjusted at anyl convenient. angle with the horizontal; third, toprovideal desk of this class which maybe variously positioned vertically with relation to its base; fourth, to provide a desk of this-class with an adjustable novelly construeted'lbook rack in connection` therewith; fifth, to provide an adjustable lamp in-con nection with said desk; siXth, to provide a deviceofV this class with novel'outward and lateral desk shifting means; seventh, to providea novelly constructed base member, and eighth, to provide a desk ofthis class `which is very simple and economical of construction, durable, portable, efficient, readilyv adjustable and which willnot readily deteric, rate or get out of order. y

lith these andl other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination andarrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended' claim` referencebeing had to the accompanying dra-wings and` to the characters of reference thereon which form a part of this application in which:

Figure 1 is a plan View of my desk with the desk portion thereof slightly extended outwardly and showing by dotted lines said desk portion extended farther outwardly and shifted laterally. Fig. 2 is a side elevational view thereof. Fig. 3 is a fragmentary sectional view taken at 3 3 of Fig.

` 2 showing the means of supporting the desk portion relatively to the shiftable supports. Fig. 41 is a sectional view taken through d-ll of Fig. 1 and Fig. 5 is a sectional view taken through 5-5 of Fig. 2.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

The cross shaped base frame l, plastic filler 2, reinforcement 3, casters l, bolts 5,

floor flange 6, upright tube members 7 and 8, wing screw 9, floor flange 10, support 11, hinged members 12, bolts 13, hinged members 111, bolts 15, hinge members 16, bolts 17, brackets 18, bolts 19, spacer 20, wing nuts 21, desk member 22, bookshelf 23, book ends 24, book and retaining clips 25 and the adjustable lamp 2G, constitute the principal parts and portions of desk structure.

The base consists of a` cross shaped inverted trough-like frame filled with a heavy lmrdening'plastic material 2, preferably concrete reinforced by mesh chicken wire 3. Said base member is provided on the lower side with revoluble'casterst secured `to said base by thebolts 5, whichare preferably cast in the base. Said base member is provided at the central portion of its upper face with theifloor flange (securedto said base member by the bolts 6rl extending therethrough; A. tube member 7 mounted in the floor flange 6` and extends upwardly therefrom or tube No. imaybe anchored in the plastic material No. 2. Said tube member is provided at its upper end with a pipe reducer 7, whichis provided witlra wing screw 9 extending therethrough and through said tube member 7. A smaller `tube member 8 is telescopically mounted in the tube member 7 and is securedltherein by the wing screw 9. On the upper end` of" the tube member 8 mounted a ioor flange 10, on the upper face of which mounted a support 11 secured tosaid floor flange by the bolts 111. Said support 11 boi;` shaped, provided with a central web and provided at its forward end with lugs 11b extending through either side thereof adapted to receive betweensaid lugs thelug portions of the hinged members 12, which members`12 are pivotally mounted in the support 11 by the bolts 13. Pivotally mounted onV the free ends of the hinged members 12 are the hinged members 1d secured to the former by the bolt 15. The hinged members 12 and 14 are provided at their connected ends with pairs of spaced apart bosses or hinge portions which are positioned intermediate each other in such a manner that the head of the bolt 15 engages the hinge portion of one hinged member, while the wing nut 15a, secured to the opposite end of the bolt, en gages a hinge portion of the other hinged member, said bolt and wing nut being adapted to hold and clamp said hinged members from being shifted readily relative to each other. The hinged members 12 are provided. at their free ends with outwardly extending lugs 12?L adapted to engage the hinged member 111 mounted therein and prevent the free ends of the hinged members 12 2y l ,f Y 1,712,814

M pivotally mounted in the other ends of the of the'swinging hinge members.

hinged members 14 and Vsecured to each Yother by the boltV 17.` Y The hinge members 16 are provided at the inside face of their other end with a plurality of radial notches 16L adapted to engage similar notches 18a on the outside faces of the brackets 18 which are secured and adapted to support the desk member 22. The bolt 19 is inserted through holes in the hinge members 16 and the brackets 18 on the underside of the desk member, permitting the desk member to be pivotally n'iounted with relation to thel horizont-al plane A tube spacer 20 is inserted between the inside faces of the bracket 18 over the bolt 19 and a wing nut 21 is rovided on the threaded end of the bolt 19'ac apted to clamp the radially notched hinge members 16 againsttheir respective brackets 18.

The book shelf 23 is secured to the upper 'face ofthe support 11 by the screws 23 and extends ysubstantially in the. same direction as the reading desk member. Said book shelf 23 isvprovided with a longitudi- V nal slot 23b approximately at the middle portion and extendingr near to either end thereof. Said bookshelf is provided with book ends 24 Which are provided at the .middleportion of their lower edges with Z-shaped clips 25 secured to said book ends by screws25a. It will be here noted that the book shelf 23 is preferably made of some resilient material so that Vthe edges making the slot 23b may be readily sprung or offset to permit the clip 25 to be inserted in said slot and to be retained by the book shelf 23.

An adjustable lamp 26 as conventionally used on various desks is supported on the support 11 and adapted to illuminate the desk portion in whatever position it may be shifted.

Though I have shown and described a particular. construction, combination and arrangement oi parts and portions I do not wish to bo limited to this particular construction, combination and arrangement hut vdesire to include in the scopeof my mven tion the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided a desk in which the desk portion may be variously shifted and positioned outwardly and laterally with relation to its support; that the desk portion maybe adjusted at any convenient angle withthe horizontal; that the desk may be variously positioned vertically with relation to its base; that there is provided a novelly constructed base.; that there is rovided a novelly constructed vbook rack an that there is provided an ad'ustable lam in connection with the des( which wiil illuminate the desk portion in whatever position it is shifted.

Having thus described my invention what nected to said first mentioned hinge members and to said support on vertical axes whereby the disk may be moved outwardly or laterally with respect to its support.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 2d B6 day of June, 1922.Y
